The result shows that this area is a t ypical reversal a ticli e structure w ith a sy cli e i the low er sectio a d a a ticli e i the upper sectio . Oil a d gas w ere ge erated i the lower sectio a d preserved i both upper a d lower sectio s. The lithologic traps were domi ated i the early period, a d both the st ruct ural a d lithologic traps were developed i the lat er period.
